Mandrake Linux Security Advisory : MySQL (MDKSA-2006:149)
Low Nessus Plugin ID 23896
Synopsis
The remote Mandrake Linux host is missing one or more security updates.
Description
MySQL 4.1 before 4.1.21 and 5.0 before 5.0.24 allows a local user to access a table through a previously created MERGE table, even after the user's privileges are revoked for the original table, which might violate intended security policy (CVE-2006-4031).
The update allows the local admin to override MERGE using the '--skip-merge' option when running mysqld. This can be defined under MYSQLD_OPTIONS in /etc/sysconfig/mysqld. If '--skip-merge' is not used, the old behaviour of MERGE tables is still used.
MySQL 4.1 before 4.1.21, 5.0 before 5.0.25, and 5.1 before 5.1.12, when run on case-sensitive filesystems, allows remote authenticated users to create or access a database when the database name differs only in case from a database for which they have permissions (CVE-2006-4226).
Packages have been patched to correct these issues.
Solution
Update the affected packages.
